Abstract
A ratchet wheel bench clamp comprises a fixed clamp body, a movable clamp body, a screw rod which fixedly connects the fixed clamp body with the movable clamp body, a ratchet wheel rotating mechanism and a rotating resistance mechanism, wherein a gear is arranged at the back end of the screw rod; the ratchet wheel rotating mechanism and the gear are in driving connection, and can drive the screw rod to rotate in an unidirectional manner; the rotating resistance mechanism is arranged between the gear and the fixed clamp body; and the resistance of the rotating resistance mechanism prevent the leading screw rotate in a reverse direction when the ratchet wheel rotating mechanism gyres. When in use, the only requirement to fasten or slacken the clamp is to enable a ratchet wheel handle to swing up and down with a small amplitude, therefore, the ratchet wheel clamp can be used very conveniently even is a place with a smaller space, thereby having a stronger practicability.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, cooperate referring to Fig. 2, ratchet bench vice of the present utility model comprises fixed caliper 1, moving caliper 2, is connected and fixed leading screw 3, ratchet rotating mechanism 4 and the rotational resistance mechanism 5 of caliper and moving caliper.Cooperation is provided with gear 31 referring to Fig. 5 in the rear end of leading screw 3, and ratchet rotating mechanism 4 links to each other with this gear drive and can drive leading screw 3 and do unidirectional rotation, and rotational resistance mechanism 5 is arranged on reverse transfer in the time of can preventing the leading screw ratchet between gear 31 and the fixed caliper 1.
Cooperation is referring to Fig. 2, and the ratchet rotating mechanism 4 in the utility model comprises ratchet handle 41, ratchet shifting block 42 and extension spring 43.Cooperation is referring to Fig. 4, and ratchet handle 41 front ends are provided with prong 411, respectively is provided with a through hole 412 on the prong biside plate.Ratchet handle is by this through hole 412 and 31 rotatable linking to each other of gear, ratchet shifting block 42 turns in the prong 411 that is installed in ratchet handle and with gear 31 transmissions by a bearing pin 44 and links to each other, one end of extension spring 43 is fixed on the ratchet handle 41, and the other end is connected on the ratchet shifting block 42.
Cooperation is referring to Fig. 2, and the rotational resistance mechanism 5 in the utility model comprises the steel ball 52 of a plurality of springs 51 and respective numbers.Cooperation is referring to Fig. 3, on the end face annulus of fixed caliper 1, be provided with a plurality of spring eyes 11, cooperation is referring to Fig. 5, on the gear medial surface annulus of leading screw 3, be provided with a plurality of grooves 32 that are used to embed steel ball, a plurality of springs 51 are arranged in each spring eye 11, and each steel ball 52 is arranged between each spring and the corresponding recesses and can rolls between different grooves.
Cooperation is referring to Fig. 6, upside at the ratchet shifting block is connected with a reversing bar protruding upward 421, the downside two ends are respectively equipped with the opposite ratchet moving tooth of direction 422,423, one end of extension spring 43 is movably connected on the reversing bar 421, ratchet shifting block 42 can make the ratchet moving tooth 423 of one end link to each other with the upside transmission of gear 31 by manual reverse of direction to carry out fasteningly to drive 3 pairs of bench vices of leading screw, or the ratchet moving tooth 422 of its other end is linked to each other with the downside transmission of gear 31 relax with 3 pairs of bench vices of drive leading screw.
