I [Prior Art] The general Taiyuan machine will have a circular saw blade in the interior of the machine. In order to prevent the mine cutting work from touching the human body, there is usually a pallet device at the back of the round ore. The pallet device can be provided with a protective cover so that the protective cover shields the circular saw blade from contacting the human body to achieve safe use. However, sometimes the table saw is protected when sawing the groove. The eye cover can hinder the cutting action, so the table saw machine usually sets the pallet device into a detachable structure, thereby achieving the effect of convenient operation. Referring to FIG. 1 , a conventional pallet device 10 includes a fixed base unit 11 , a holder unit 12 movably disposed on the fixed base unit u , and a fixed seat unit u and a holder unit 12 . The control unit 13 has a fixing base 111 fixedly attached to a machine table (not shown). The fixing base 1U is recessed at one side for a clamping seat unit 12 In the sliding slot 112, the holder unit 具有2 has a clamping piece 121 (four) clamping piece 121, embedded in the center of the missing piece 121: a first cam 122, and a fixed protrusion in the clip The stop pin 123 at the outer side of the holding piece 121 has a shaft member 131 disposed at the center of the missing piece 121, and is fixed to the shaft member ι31 and coupled with the first cam 122. a second cam 132, a handle 1314894 disposed on the second cam 132, a handle 133, and a limiting flange 134 protruding from the operating handle 133 to collide against the stop pin, the clamping piece 121 and the sliding The side wall of the slot ιΐ2 is placed for the lower edge of a pallet 1 and the cup is extended! μ The top edge of the Haitu board 1 is available - the eye cover (not shown) is installed.

On, when the user turns in a clockwise direction; At 33 o'clock, the first and second cams 122, m can be brought close to each other, and the clamping piece (2) is moved away from the fixing seat (1) to release the pallet 1, so that the protective cover can be self-operated Disassemble and separate them. Although the above-mentioned pallet device 10 has the function of being assembled and disassembled (four), there is still a need for improvement in the use thereof, since the pallet 1 is fixed by the clamping piece 121 and is fixed, and the η θ 符 121 121疋^The second cam 132 pushes the first cam 122 to generate the urging motion, and the first and second cams 122, 132 are slightly insufficient. If the movement amount of the first and second cams 122, 132 is slightly insufficient, the holding piece 121 is opposite to the pallet 1 The clamping force will be small, the fixing effect of the pallet 1 is poor, and the pallet 1 is prone to slack and looseness, especially when the table saw is vibrating during the cutting operation, the pallet device 1 is easily caused by the jitter. The first and second cams 122 and 132 return to the kneading position in the same direction, and the clamping piece 121 is completely loosened. In the worst state, the pallet 1 may even fall off, causing troubles in use. Referring to FIG. 2, another conventional pallet device 2〇 also includes a solid housing unit 21, a pallet unit 22 and a control unit 23, which is different from the previous pallet device 1 . The seat unit 21 has a fixing base 211 and a C-plate 212. The pallet unit 22 has a clamping seat 2 ι and 1314894.

When the user wants to adjust the tray 41 downward to the hidden state, the user wants the tray 41 to be bred first, and the 0 士# + state refers to FIG. 7 and FIG. , σ f / needle direction turns the steering handle 63, the first cam 61 is subjected to the spring, and is reversed to move in a direction away from the pallet 41, and the first wedge portion 613 and the first cam 61, 62 622 are mutually The splicing plate 41 can be relaxed and lively „. The pallet 41 can be 'simultaneously' the baffle 71 is driven by the elastic element 1111 1314894, which will drive the 疋 position of the 销 position pin 73 from the pallet 41 The first inner detachment, such as the boring hole 412, the user can grasp the pallet 41 to move up and down along the @ freely. & 疋 31 31 Referring to Figures 9 and 10, when the user will hold the pallet 41 When descending to the second position π of the obstacle barrier state, use "falling to reach the hidden shape 63, the second w" To the crank handle 262, the wedge portion 622 of the wheel 62 pushes the first mold portion (1)' inwardly to cause the first cam 61 to be pressed by the top cymbal. At this time, the first ping "4" and the pallet The relationship that the first cam 62 is pushed outward relative to the first cam will drive the shaft θ move shaft 70 member 32 together with the baffle 71 to move toward the bracket 41 (toward the (4) inlet plate 41 The first = ^ 1 ± 6 ^ _ _ 73 just seat 弹 and the shrapnel 64 double sided ^ inside, the pallet 41 is fixed above, the storage of the visor of the present invention is required to set the main θ The second main X uses the first cam 62 to push the first cam 61 or: the action 'returns the first cam 61 through the elastic cymbal cymbal to perform the pressing action on the pallet 41: Thus, the present invention can utilize the reverse of the steering handle 63. The direction rotation control tray 41 is in a relaxed or fast state, and the operation is quite quick and convenient. 'The pallet 4i is very easy to find the loading and unloading action, and the second setting 73 is inserted into the pallet 41 first, the second positioning hole 412, 413, the quasi-shilin is positioned in the protruding or hidden position. Most importantly, the hair piece 64 is inwardly and outwardly biased by the elastic piece 64. 1 and the first cam & the projectile is powerful enough to eliminate the problem that the first and second cams 61, 62 are insufficiently displaced, and provides the best line force to the pallet 41 even if the table (four) (10) is at 12 1314894 The long-term vibration does not cause the pallet 41 to loosen. Therefore, the present invention has an excellent fixing effect in particular.
