DETAILED DESCRIPTION

[0017] The utility model is further explained below in combination with the drawings.

[0018] As Figure 1 , Figure 2 , Figure 3 Indicated, a joint machine handle reversing device, the handle reversing device includes steering seat 7, and the steering seat 7 is installed on jaw frame 10;Steering lever 5 is rotatably installed in the steering seat 7, and the lower end of the steering lever 5 is provided with semicircular limit baffle 9 for realizing the unloading of joint machine main pincer, and the semicircular limit baffle 9 is matched with reversing pin 11 installed on gear ring 12;The upper end of the steering lever 5 is connected with steering disc 6, and the other end of the steering disc 6 is installed with handle 1. By moving handle 1 on steering disc 6, steering disc 6 drives steering lever 5 to rotate in steering seat 7, and the semicircular limit baffle 9 on steering lever 5 is reversed, so that the unloading of joint machine main pincer is realized.

[0019] As Figure 1 Indicated, spring 2 and cylindrical pin 3 are sequentially installed in the steering disc 6, and the other end of the cylindrical pin 3 is matched with ring groove 8 or limit deep circular groove 4 symmetrically arranged on the outer periphery of steering seat 7. It is guaranteed that steering disc 6 can stably drive steering lever 5 to rotate in steering seat 7 and slide limit.

[0020] By moving the handle 1 on the steering wheel 6, the cylindrical pin 3 extrudes the spring 2 from the limiting deep circular groove 4 on the steering seat 7 and slides in the ring groove 8, so that the steering wheel 6 drives the steering rod 5 to rotate in the steering seat 7 until the cylindrical pin 3 slides to another limiting deep circular groove 4, and the reversing of the semicircular limiting baffle 9 on the steering rod 5 is completed.

[0021] As shown in Figure 2 , Figure 3 , the positioning pin 11 is limited by the pin groove 13 opened on the jaw plate 10.

[0022] The working process of the utility model is as follows:

[0023] As shown in Figure 2 , Figure 3 , the main wrench of the screwing machine mainly comprises a large gear ring 12, a reversing pin 11, a jaw plate 10, a slope plate 16, a jaw plate 15 and a tension spring 14. The slope plate 16 and the reversing pin 11 are mounted on the large gear ring 12, the jaw plate 10 is provided with the pin groove 13 and is mounted with the tension spring 14 and the jaw plate 15, the reversing pin 11 is limited by the pin groove 13 opened on the jaw plate 10, and the position of the jaw plate 15 and the slope plate 16 is as shown in Figure 3 . When screwing, the large gear ring 12 rotates to drive the slope plate 16 to rotate, meanwhile, the jaw plate 10 and the jaw plate 15 are stationary, the reversing pin 11 slides in the pin groove 13, when the reversing pin 11 is on the P position of the pin groove 13, the slope plate 16 forces the jaw plate 15 to climb, under the action of the tension spring 14, the jaw plate 15 extends to complete clamping and rotates together with the jaw plate 10 to realize the screwing function. After the screwing is completed, the large gear ring 12 reverses, the jaw plate 15 retracts until the reversing pin 11 is on the semicircular limiting baffle 9 groove of the handle reversing device, the jaw plate 15 completely retracts, if there is no semicircular limiting baffle 9 limiting, the jaw plate 15 climbs overshoot, repeatedly climbs and retracts, which affects the service life and has certain safety hazards. When unscrewing, the handle 1 is moved, the semicircular limiting baffle 9 groove is on the other side, and the same principle is that the large gear ring 12 rotates, the reversing pin 11 slides in the pin groove 13 and is on the K position to complete the clamping of the jaw plate 15 for unscrewing; after the unscrewing is completed, the large gear ring 12 reverses, the reversing pin 11 slides and is on the semicircular limiting baffle 9 groove again, and the jaw plate 15 completely retracts. Therefore, the utility model completes the screwing and unscrewing of the main wrench of the screwing machine.
