Preferably, a hole is formed in the middle of the special-shaped nut, and the adjustable telescopic stop lever is fixed on the special-shaped nut through the clamping screw rod.
Preferably, the annular holding clamp is provided with more than two sections of arc structures to form an annular shape, and the arc structures are connected through hinges and threaded fasteners.
Preferably, the threaded fastener comprises a stud and a wing nut.
Preferably, the annular inner clamping ring is provided with teeth.
Preferably, the adjustable telescopic stop lever is provided with an outer stop lever and an inner stop lever, the outer stop lever is hollow, the inner stop lever is arranged in the outer stop lever, and the inner stop lever can extend out of the outer stop lever and is fixed through a fastener.
The utility model has the advantages that:
the utility model discloses having changed the method of traditional dismouting sucker rod, having really realized the purpose that reduces the operator, reached alone and can accomplish many people's collaborative work, the clamp does not drop, and the work that alleviates the operator is slight, improves work efficiency. The utility model adopts the clamping screw rod and the butterfly nut at the connecting part, thereby being convenient for clamping and reliable in action; the adjustable telescopic stop lever can be used for prolonging the operation according to actual needs, and effectively deals with various actual working conditions.

Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic structural view of the annular fixing device of the present invention.
Description of the symbols of the drawings:
1. an annular fixture; 2. a special-shaped nut; 3. an adjustable telescopic stop lever; 11. a guide sleeve; 12, clamping a screw rod; 13. a connecting plate; 14. annular clasping; 15. a butterfly nut; 16. a stud.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples, so that those skilled in the art can easily implement the present invention.
Example 1: as shown in fig. 1, the utility model discloses be equipped with annular fixing device 1, abnormal shape nut 2 and adjustable flexible pin 3, adjustable flexible pin 3 is circular long and thin rod-like structure, and abnormal shape nut 2 is equipped with to one end, and the other end has set firmly circular separation blade, slides in the middle of the adjustable flexible pin 3 and is equipped with annular fixing device 1. The middle of the special-shaped nut 2 is provided with a hole, and the lower end of the adjustable telescopic stop lever 3 can be inserted into the hole of the special-shaped nut 2 and fixed through a clamping screw rod.
The adjustable telescopic stop lever is provided with an outer stop lever and an inner stop lever double-layer structure, the inner stop lever is arranged inside the hollow outer stop lever, and the inner stop lever can be pulled out from the outer stop lever and is fixed through knob rotation.
As shown in fig. 2, the annular fixing device 1 is provided with a guide sleeve 11 and an annular clamp 14, and the guide sleeve 11 and the annular clamp 14 are fixedly connected through a connecting plate 13; the guide sleeve 11 is sleeved at the long rod of the adjustable telescopic stop lever 3, the guide sleeve 11 is provided with a clamping screw rod 12, and the guide sleeve 11 and the adjustable telescopic stop lever 3 can be limited to slide relatively by rotating the clamping screw rod 12, so that the annular fixing device 1 is fixed relative to the adjustable telescopic stop lever 3. The annular holding clamp 14 is of a three-section type circular arc structure and forms a circular ring shape, teeth are arranged on the inner ring, two ends of a circular arc fixed with the connecting plate 13 are connected with the other two sections of circular arcs through hinges, the other ends of the two sections of circular arcs which are not directly connected with the connecting plate 13 are respectively provided with a stud 16 and a stud inlet and outlet channel, the stud 16 is hinged with the annular holding clamp 14, the stud 16 is provided with a butterfly nut 15, the stud 16 is screwed with the butterfly nut 15 after entering the stud inlet and outlet channel, and the three sections of circular arcs of the annular holding clamp 14 can; the wing nuts 15 are loosened, and the studs 16 exit the stud access passages, so that the two arcs which are not directly connected with the connecting plate 13 are separated from each other.
During operation, 1, fixing the special-shaped nut 2 at the bottommost part of the utility model on a slip bolt at the lower part of a well head, and then inserting the lower end of an adjustable telescopic stop lever 3 into a hole of the special-shaped nut; 2. fixing an annular fixing device 1 positioned at the upper part of an adjustable telescopic stop lever 3 on a short section at the upper part of a wellhead, and fixing and locking an adjusting butterfly nut 15; 3. the adjustable telescopic stop lever 3 is adjusted up and down to a proper height and fixed by a clamping screw rod 12 until the installation is finished.
