[0012] Further, the length of the vertical part is greater than the length of the pointed end part.

[0013] Further, the two support parts are provided with blades at opposite positions, and the edges of the two blades are opposite.

[0014] Further, the abutting seat is square.

[0015] Further, a spring is arranged between the first handle and the second handle.

[0016] Further, anti-skid sleeves are arranged on the first handle and the second handle.

[0017] The working principle of the utility model is as follows:

[0018] According to actual conditions, appropriate tongs are selected, for example, when the bearing and the snap spring 7 are axially horizontal, the pointed end part 3 can be used as the tongs at this time, the tool is in a horizontal state, and the snap spring 7 is disassembled and assembled, in this form, the hand is convenient for holding the handle and the opening and closing of the pointed end part 3, and operation is facilitated.

[0019] The sleeve function: the hollow sleeve extension rod 8 can pass through any vertical part 5 and abut against the abutting seat 42, and different sleeves are installed on the sleeve extension rod 8, so that screws of different shapes and different sizes can be taken out.

[0020] Compared with the prior art, the utility model has the beneficial effects that:

[0021] (1) The multifunctional bearing snap spring and screw extractor provided by the utility model has the functions of disassembling and assembling the snap spring and the screw, can reduce the burden of carrying tools, improve work efficiency, and has high universality.

[0022] (2) According to actual conditions, the pointed end part or the vertical part can be selected to disassemble and assemble the snap spring, so that the convenience of the snap spring is effectively improved. DRAWINGS

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] like Figure 1 As shown, this embodiment provides a multifunctional bearing retaining ring and screw remover, including: a symmetrical first body and a second body, which are hinged by a pin to form a scissor structure. One end of the first body is a first clamp 11 and the other end is a first handle 12. One end of the second body is a second clamp 21 and the other end is a second handle 22. Anti-slip sleeves are provided on both the first handle 12 and the second handle 22 to prevent slippage. A spring 6 is provided between the two to allow for automatic rebound after being subjected to force.

[0033] Specifically, both the first clamp body 11 and the second clamp body 21 include: a tip 3, a support 4, and a vertical part 5. The tip 3 is located at the front end of the first clamp body 11 / second clamp body 21 and has a conical structure to facilitate the installation and removal of the retaining spring 7. The tip 3, together with the first and second bodies, forms a horizontal structure, such as... Figure 2 As shown, it can be used to disassemble and install the circlip 7 in the bearing and circlip 7 in the horizontal direction. The tip 3 is used as the pliers head. The tool is horizontal in shape and moves in the horizontal direction. It is easy for the hand to hold the handle and for the tip 3 to open and close.

[0034] The support part 4 is the connection part between the tip part 3 and the handle. Two blades 41 are arranged between the two support parts 4. The cutting edges of the two blades 41 face each other to form a cutting structure, which is convenient for daily cutting and does not affect the normal operation of the tip part 3.

[0035] like Figure 3As shown, the vertical part 5 is provided on the support part 4 and arranged perpendicular to the support part 4. The vertical part 5 is conical in shape, and its length is greater than that of the tip part 3. It can be used to handle the retaining rings 7 that are located deep inside. The longer vertical part 5 allows for the assembly and disassembly of retaining rings 7 that are located deeper and are more difficult to operate. In addition, for equipment where the bearing and retaining ring 7 are axially vertical, when the retaining ring 7 is clamped by the vertical part 5, the tool as a whole can still remain horizontal, which is convenient for gripping and applying force.

[0036] like Figures 4-5 As shown, a docking seat 42 is provided at the connection of the support part 4. The docking seat 42 is a square shape that is adapted to the sleeve extension rod 8. The sleeve extension rod 8 can be inserted into any vertical part 5 and docked with the docking seat 42. Different sleeves can be installed on the sleeve extension rod 8, so that screws of different shapes and sizes can be taken out.

[0037] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
