the first placement block 202 Round hole, the bottom right face of the second placement block 203 are provided with round hole, and the first placement block 202 and the second placement block 203 are worn by screw The upper surface that round hole is fixedly connected on placement plate 201 is crossed, block 202 and second is placed first and places the lower end setting of block 203 Have and place limit plate 204, place the upper surface that limit plate 204 is fixedly connected on placement plate 201 by screw, first places block 202 and second placement block 203 and place limit plate 204 among be provided with interval, tool tong 40 and rubber sleeve 50 assembling mistake Cheng Zhong, the first interval placing block 202 and the second placement block 203 and placing among limit plate 204 can be in reply tool tong 40 Handle have different radians in the case where, carry out automatic angular adjustment, prevent tool tong 40 and rubber sleeve 50 in assembling because For placement section 20 can not automatic adjusument, form rigid assembling, cause the product quality assembled clumsy, simultaneously as just The assembling of property damages reduction service life to each components of toggle device, and the placement limit plate 204 of setting also can be First placement block 202 and the second placement block 203 also have a supporting point when carrying out adaptive angular adjustment, make 40 He of tool tong Rubber sleeve 50 can assemble, and also can effectively be coped with by separated placement block, with different length tool tong 40 handle, into It is easily assembled when the assembling of row rubber sleeve 50.The upper surface that pressing portion 30 is fixed on bottom plate 10 by sliding rail 304, slides rail 304 upper surface is provided with sliding panel 301, and sliding panel 301 is fitted in the outer of sliding rail 304 by the rectangle sliding block of lower surface Portion is provided with arc-shaped slot for placing ball 305 in the left and right sides of sliding rail 304, while being provided with sliding in the inner wall of sliding block Slot 306, ball 305 are wrapped up by sliding rail 304 and sliding groove 306, are pushed away by 305 sliding panel 301 of ball to placement section 20 The more convenient propulsion of energy, is fixedly installed push plate 302, push plate 302 by screw in the upper surface of sliding panel 301 when pressure Inside is provided with the slot that 40 heads are clamped for being adapted to place tool, and in the upper end of push plate 302, setting, which is equipped with, pushes limit plate 303 Prevent push plate 302 from loosening the product quality clumsiness after leading to assembling when being promoted for pressing portion 30, in pressing portion 30 Upper end be connected with pushing meanss 60 for pushing to pressing portion 30,60 upper end of pushing meanss is provided with regulation handle 80, Stroke adjustment can be carried out to pushing meanss 60 by regulation handle 80, toggle device is made to adapt to the tool tong of different length handle 40 carry out the assembling of rubber sleeve 50.Worker can be facilitated to carry out tool tong 40 and rubber by the combination of placement section 20, pressing portion 30 The amount of labour is reduced in the assembling of gum cover 50, is not necessarily to worker's assembled by hand, worker is reduced and is damaged caused by hand in long-term assembling Wound, improve tool tong 40 and rubber sleeve 50 assembling integrality, enable tool tong 40 and rubber sleeve 50 more accurately install and Positioning, while the product quality after being completed can be made to be consistent substantially by the assembling of machine.By placement section 20, push Portion 30, pushing meanss 60 and regulation handle 80 can make whole device form semi-automation, reduce the amount of labour of worker, improve work Efficiency, keep tool tong 40 and rubber sleeve 50 more convenient in assembling, can tool tong 40 to different decreased foods carry out With the assembling of rubber sleeve 50, service life is improved.201 thickness of placement plate of placement section 20 is slightly rear and slides rail 304, so that placing Portion 20 can be higher than sliding rail 304, and when pressing portion 30 is promoted, tool tong 40 can be anti-with a certain distance with sliding rail 304 Sliding rail 304 is only collided when the tool tong of different model 40 and rubber sleeve 50 assemble leads to the damage for sliding rail 304.(such as Shown in Fig. 5) under the propulsion of pushing meanss 60, pressing portion 30 makes the handle of tool tong 40 be inserted in rubber sleeve close to placement section 20 Assembling is completed in 50, reduces manual labor amount, and the product quality after improving work efficiency while assembling is relatively uniform, reduces people The injury of work hand.
Finally, additionally providing a kind of application method of automatic toggle device of tool tong as in Fig. 6,7, comprising the following steps:
It prevents from covering by the way that the inside that the handle end of tool tong 40 is partially placed into rubber sleeve 50 is first manually formed pre-installation Tool tong 40 and rubber sleeve 50 separate when handle device operates;
Then tool tong 40 and rubber sleeve 50 are respectively put into 301 slot of sliding panel of pressing portion 30 and placement section 20 is put It sets in 201 slot of plate, tool tong 40 and rubber sleeve 50 can be made to be fixed in the slot of pressing portion 30 and placement section 20, make tool tong 40 Movement will not occur in assembling with rubber sleeve 50 causes last completed knocked down products quality clumsy;
Then starter 90 is manually pressed;
Then pressing portion 30 pushes the handle of tool tong 40 into rubber sleeve 50 under the advancing movement of pushing meanss 60 Portion, placement section 20 provide the assembling that supporting point facilitates tool tong 40 and rubber sleeve 50;
Then tool tong 40 and rubber sleeve 50 take out after being completed, and repeat the above steps and carry out secondary assembling.
It further, can be by adjusting handle after tool tong 40 and rubber sleeve 50 are put into pressing portion 30 and placement section 20 Hand 80 carries out the adjustment of stroke to device.Can enable device should tool tong 40 to different decreased foods carry out and rubber sleeve 50 Assembling, reduce the cost of device.
Although the illustrative specific embodiment of the application is described above, in order to the technology of the art Personnel are it will be appreciated that the application, but the application is not limited only to the range of specific embodiment, to the common skill of the art For art personnel, as long as long as various change the attached claims limit and determine the application spirit and scope in, one It cuts and is created using the application of the application design in the column of protection.
