1. The concept and function of spike pry picture
 The spike pry picture is a common tool used to pry off various closed spike locks or other fasteners, which is used to facilitate disassembly and repair work. The picture of the spike pry is generally composed of a handle and a crowbar. The handle is the part that can be held by human hands, and the crowbar is the part used to pry the nail lock or other fasteners.
 The main function of the spike pry picture is to help users easily remove various locks or other fixed devices, such as door locks, window locks, box locks, etc. Traditional spike pry pictures are mostly made of metal. After special treatment, it has high wear resistance and corrosion resistance, and can maintain good performance in long-term use.
 The spike pry picture has a wide range of applications, not only for maintenance and disassembly in the home, but also for maintenance and repair of machinery and equipment in the industrial field. Because of the portability and practicability of the picture of the spike pry, it has become one of the necessary tools for many people.
 2. Principle and structure of spike pry picture
 The principle of the spike prying picture is to use the lever principle to transform the human force into prying force through the lever arm provided by the handle. The structure of the utility model mainly comprises a handle and a crowbar.
 The handle is usually made of plastic. People can hold the handle and transfer the force to the crowbar by applying force outward. The crowbar is generally made of metal, which has certain strength and toughness and can withstand greater force.
 In the design of the spike pry picture, there is usually a connection node between the handle and the crowbar to ensure the stable connection between them. In addition, the shape and length of crowbars will also vary according to different use needs. Some crowbars have special bending angles or shapes to adapt to the use of different angles and spaces.
 3. How to use the picture of spike pry
 When using the picture of the spike pry, first determine the type of locks or other fixtures that need to be removed or repaired, and select the appropriate picture of the spike pry. Then follow these steps:
 1. Hold the handle of the spike pry picture to ensure a comfortable grip.
 2. Insert one end of the crowbar into the gap of the spike lock or other fasteners.
 3. Use the lever principle to apply force outward to pry the spike lock or other fasteners open gradually.
 4. If you encounter greater resistance or cannot pry, you can try to adjust the position or angle of the crowbar, and apply force again from another angle.
 5. After successfully prying the spike lock or other fasteners, maintenance, replacement or other necessary operations can be carried out.
 It should be noted that excessive force should be avoided when prying pictures with spikes to prevent damage to locks or other fixtures. In addition, it is necessary to maintain a stable action when using the spike pry picture to avoid sliding or losing control during the operation.
 4. Advantages and limitations of the picture of the spike pry
 As a common tool, the spike pry picture has the following advantages:
 1. Easy to use: The picture of the spike pry is simple to operate, and the user only needs to operate according to the basic use method.
 2. Versatility: The picture of the spike pry can not only remove various closed spike locks, but also be used for the removal and maintenance of other fasteners.
 3. Portability: The picture of the spike pry is small and easy to carry. It can be put into the pocket or toolbox and used anytime and anywhere.
 However, there are some limitations in the picture of the spike pry:
 1. There are certain technical requirements: although the picture of the spike pry is simple to use, the operation requirements for some complex locks or other fixed devices are high and require some technical experience.
 2. Potential safety hazard: if used improperly or applied with excessive force, the picture of the spike pry may damage the lock or other fixed devices, leading to potential safety hazard.
 summary
 The spike pry picture is a common tool used to pry open various closed spike locks or other fasteners. It realizes the transformation of power through the lever principle, which is convenient to use, multifunctional and portable. However, certain technical requirements are required for the operation of complex locks, and improper use may bring potential safety hazards. Therefore, it is necessary to operate carefully when using the spike pry picture, and seek professional help when necessary.
