Then, from the state shown in Fig. 5 As a result of turning the operating handle 4, the movement to the initial state shown in FIG. 3 again. At this time, the curvature of the outer periphery of the first and second lever cams 3a, 3b is kept constant, which can be smaller than the conventional example. In addition to the original strength, when the first and second plate cams 3a, 3b are worn due to repeated crimping operations, a certain amount of clamping can be ensured, and the durability of the crimping tool can be improved. As described above, in this embodiment, the handle can be turned three times to complete a crimping operation. The number of operations of the handle 4 can be set arbitrarily. However, in order to effectively complete the crimping operation, it is about 2 to 4 times. Operation is appropriate.

Explanation of the invention (As the handle 4 can be crimped by operating the handle 4 multiple times, compared with the previous & the opening angles of the handles 4, 5 are reduced. Therefore, it is not necessary to change the handle 4 in the crimping operation. The holding position of '5 can not only improve the operation of the splicing operation, but also effectively suppress the occurrence of dust connection failures. Moreover, the crimping operation at the Nakagori Institute can be easily performed. The structure of the plate cam according to the present invention will be described in detail with reference to FIG. 6. FIG. 6 is a plan view of the second plate cam flutter with the invention. Moreover, the first plate cam 3 a also has the same structure. The shape of the plate cam ⑼ f 2 has a protruding part fluttering locally in the radial direction.] The construction is provided with 4 protrusions plus. The center of the second plate cam flutter is provided with a through shaft that can accommodate the camshaft. As shown in the figure, the protruding portion 3M has a first outer periphery 'edge portion 3bl extending from the front end to the second plate cam outer periphery 1! ^ 20 and a first outer periphery 3bn extending from the first r. The curvature is set to = the curve of the second outer periphery 3bl2 near the base of the dog out 3bl Because the outer periphery 3bl1 is the head of the second crimp terminal of the crimp terminal: 22 The outer periphery 3bl2 clamps the movement of the first and second head members 2a and 2b before the terminal is repeatedly connected. The reason is that Μ = The peripheral edge plus 1 is set to a relatively small curvature, which can reduce the instantaneous force when clamping the connection terminal, which can be used to handle it. Also, the second outer periphery near the base 31) As a result of the pair of 12 songs being large, the amount of displacement of the two parts that are the same as the common parts before clamping the terminal can be increased, and the 12th can be shortened until the terminal is properly crimped. Page 417343 V. Description of Invention (ίο) Time required. In addition, as shown in FIG. 5 'because a part of the first outer peripheral edge 3bll close to the front end of the protruding portion 3bl is formed by an arc', it is not necessary to use a larger size after the crimp terminal is pre-compressed. It is necessary to hold the handles 4 and 5 with less power, and it can use less power than before, and automatically restore the phase state. Therefore, when the plate cam according to the present invention is used, the crimping operation can be performed efficiently and easily. As shown in Fig. 6, each of the protruding portions 3bl is set within a range of approximately 90 degrees. Therefore, as described above, turning the handle 4 three times can make the second plate cam 3b rotate 30 degrees each time to complete a crimping operation. Next, another characteristic part of the crimping tool 1 according to the present invention will be described with reference to Fig. 7 as follows. FIG. 7 is a partial side view of the crimping tool 1 viewed from the handle 5 side. The first and second plate cams 3a, 3b are placed in a positional relationship in which they overlap each other at intervals. Then, a pair of rollers 16a are provided in a state of being in contact with both of the first and second plate cams 3a, 3b. The second roller 16b is also provided as a pair above and below the second head member 2b, and is in contact with both the first and second plate bosses 3a, 3b. As described above, the results of the first and second rollers 16a and 16b being connected to both of the first and second plates Λ and 3a and 3b can be obtained on the periphery of the first and second rollers 16a and 16b. Slide the first and second plate cams stably. Therefore, the first and second head members 2a and 2b can be smoothly rotated, and the crimping operation can be performed with high efficiency and accuracy. In addition, the relationship between the first and second master members 2a, 2b can be supported by both the first and second plate cams 3a, 3b.
