In order to realize the purpose, the technical scheme of the utility model is that:

a clamp spring dismounting clamp comprises two strip-shaped clamp bodies, wherein the strip-shaped clamp bodies are provided with cylindrical head clamp mouths and are respectively called as a positioning clamp body and a sliding clamp body, the two sides in the middle of the length direction of the positioning clamp body are respectively and fixedly provided with a sliding rod which is vertical to the positioning clamp body, the two sides in the middle of the length direction of the sliding clamp body are respectively provided with a through hole, the sliding clamp body is sleeved on the two sliding rods in a sliding way through the through holes, the middle of the positioning clamp body between the two sliding rods and the middle of the sliding clamp body are respectively and oppositely provided with a thread through hole, the threads of the thread through holes on the positioning clamp body and the sliding clamp body are mutually reverse threads, a screw rod with positive and negative threads at two end sides is respectively screwed into the two thread through holes of the positioning clamp body and the sliding clamp body from the position between the positioning, a handle interface is arranged at one end of the screw rod, and the screw rod is rotated in the positive and negative directions by inserting the handle into the handle interface to drive the sliding clamp body to move back and forth along the sliding rod so as to disassemble and assemble the inner clamp spring and the outer clamp spring.

The scheme is further as follows: and a hand-held handle is arranged on the positioning clamp body and used for holding the clamp spring dismounting clamp.

The scheme is further as follows: a positive and negative thread separating ring is arranged between the positive and negative threads on the two sides of the screw.

The utility model discloses an useful part is: the clamp spring dismounting clamp has the advantages that the positive and negative rotating screw rods are utilized, so that two strip-shaped clamp bodies are relatively or mutually displaced under the constraint of the sliding guide rail, the clamp spring can be kept in an open or tightening state, the elastic clamping ring for the large-diameter shaft and the elastic clamping ring for the large-diameter hole can be dismounted, the operation is convenient, the labor force is saved, and the potential safety hazard of work is eliminated.

The present invention will be described in detail with reference to the accompanying drawings and examples.

Drawings

fig. 2 is a schematic diagram of the operation of the present invention.

Detailed Description

As shown in figure 1, the side surfaces of the two elongated pliers bodies are provided with an upper through hole, a middle through hole and a lower through hole which are parallel to each other, the upper through hole and the lower through hole are unthreaded holes, and the middle through hole is a threaded hole and is a thread which is opposite to each other. The two strip-shaped pliers bodies can be formed by dividing the whole pliers body into two independent left and right strip-shaped pliers bodies on the central symmetrical plane of the surface of the whole pliers body. The left clamp body 2 is called a sliding clamp body, the right clamp body 3 is called a positioning clamp body, the top surfaces of the left clamp body and the right clamp body are respectively provided with a cylindrical clamp mouth 201 and a cylindrical clamp mouth 301, slide bars 6 are arranged in upper holes and lower holes of the left clamp body and the right clamp body, the slide bars 6 are fixedly connected with the right clamp body 3, and screw rods 1 are screwed in middle threaded holes of the left clamp body and the right clamp body. The two ends of the screw rod 1 are respectively provided with positive and negative threads, one of the two front surfaces of the left and right clamp bodies is provided with a fixed hand-held handle 5 for holding the clamp spring dismounting clamp, and the hand-held handle 5 shown in figure 1 is arranged on the right clamp body. The threads of the threaded through holes of the middle holes of the left forceps body and the right forceps body are mutually reverse threaded through holes, one of the rotation directions is left-handed and the other is right-handed. One end of the screw rod 1 is provided with a rotary handle interface which is used for connecting a wrench 4. The middle part of the screw is provided with a positive and negative thread separating ring 101, and both sides of the thread separating ring 101 are respectively provided with a left-hand thread and a right-hand thread which are matched with the internal threads of the middle hole of the left clamp body and the right clamp body. The thread separating ring 101 of the screw rod is positioned in the middle of the left clamp body and the right clamp body, and the thickness of the thread separating ring is 1-2 mm. The

cylindrical head jaw

201, 301 is tangent to the central symmetry plane of the front surface of the jaw body.

The utility model discloses an operating method: as shown in fig. 2, one hand holds the fixed handle 5, the other hand rotates the wrench 4, the wrench 4 rotates to drive the screw 1 to rotate, the left caliper body 2 and the right caliper body 3 on the guide rail slide bar 6 are closed to the center, and the two

cylindrical caliper mouths

201 and 301 are inserted into the holes of the elastic collar 7. The wrench 4 is rotated reversely, the two

cylindrical head jaws

The double-rotation-direction screw rod type large-diameter shaft elastic clamping ring has the advantages that the double-rotation-direction screw rod is utilized to enable the two strip-shaped clamp bodies to move oppositely or back to back under the constraint of the sliding guide rail, and the large-diameter shaft elastic clamping ring and the large-diameter hole elastic clamping ring can be disassembled and assembled.

The cross section of the sliding rod 6 is circular or square, and the same ends of the two guide rail sliding rods are fixed with the right clamp body 3 through screws, so that the clamp spring dismounting clamp has the advantage of more stable structure; the thread separating ring 101 in the screw 1 is located at the center position between the left forceps body 2 and the right forceps body 3, and when the screw is rotated, the left forceps body 2 and the right forceps body 3 can be folded at two sides of the thread separating ring at the same time. The advantage of setting up like this can guarantee that the distance after two cylinder

head pincers mouths

201, 301 draw in satisfies the operation requirement.
