Description

Hand tool

Technical field

The utility model relates to a kind of hand tool, belongs to the machine tool field, belongs to the electrician testing tool technology field of mainly using with manual mode in the machine tool specifically.

You Zhike is provided with the device of ratchet-type stopper unit on hand-held tool, utilize ratchet-type stopper unit to do the spacing use operation of direction for hand-held tool, reaches the turn blocking function of ratchet.

Background technology

Work implements operation at machinery, maintenance, the installation of member, the operation procedure that group is upright and relevant etc., use various instrument through regular meeting, tool or cutter, and in many hand-held tools, the how also quite frequent person of utilization rate, spanner as the rotation screw head, the profile that must cooperate screw terminal is to select suitable hand-held tool for use, wherein the spanner that the most generally uses then has monkey wrench, quincunx spanner, die nut etc., but various spanners in use, can be because of the angle of rotation or stopping of peripheral utensil, and using the rotation that sees through repetition when operating, withdraw from, contraposition is embedded, rotation, reach the action of screw being done locking or removal, operator scheme so, with the operation inconvenience that causes when using spanner, that repeats withdraws from, contraposition is chimeric to be waited after the action, consumed the considerable time with artificial, the dealer is then arranged in order to solve the puzzlement of inconvenience when hand-held tool uses, and develop the different rotary direction of utilizing ratchet, reach the purpose of rotation or blocking, but when using ratchet spanner, often to utilize the collocation of handle and sleeve to use, with handle rotation and rotate locking screw or take out screw of driving pawl in the same way; So so process operation step, formality must be used multiple instrument and collocation apparatus, and quite trouble and inconvenience seem in the use.

There is the dealer to develop the instrument of hand-held tool being done combination, as several M310775 number " brake structure of ratchet spanner " novel patent of certificate number, lie in and filed an application on November 17th, 2006, application case number No. 95220326, and the neck card is announced in the patent gazette on May 1st, 2007, see also shown in Figure 8, the three-dimensional exploded view of brake structure is commonly used by system, it is characterized in that: have storage tank A1 on the wrench body A, and be laid with ratchet A11 at storage tank A1 periphery, the bottom land of storage tank A1 and groove top have a stopper slot A12 who excises outward, A13, braked wheel B inside provides the well B1 of card knot tool heads, the then impartial breaker slot B2 that is concaved with number by little gradually big arcuation extension of periphery circle, the incline position of breaker slot B2 minimum is card knot face B21, the card knot face B21 direction of each breaker slot B2 is set to a good luck direction of rotation, and breaker slot B2 the opposing party has fixing groove B22, the root edge outer peripheral edges ring of braked wheel B is protruding with support portion B3 in addition, the sour jujube piece C outside is for cooperating the card knot face B21 of breaker slot B2, card knot face C1 is set, side is provided with ratchet C2 in addition, and the card of sour jujube piece C knot face C1 end opposite has a fixing groove C3 in addition; Then braked wheel B is inserted by the storage tank A1 below of wrench body A, and utilize support portion B3 to cooperate with the stopper slot A12 of storage tank A11 bottom, sour jujube piece C and elastic parts C4 are placed among each breaker slot B2 of braked wheel B in regular turn, elastic parts C4 two limits are placed among the fixing groove B22 spacing respectively, and with the past extrapolation of sour jujube piece C, the card knot face C1 of sour jujube piece C is cooperated with the card knot face B21 of braked wheel B, and the ratchet C2 of sour jujube piece C cooperates with the ratchet A11 of wrench body A, it is fixing to be covered on the stopper slot A13 place, storage tank A1 groove top of wrench body A with fixing ring cowling D again, fixedly ring cowling D and with the cavity ring place for the support of braked wheel B top; Right this brake structure of commonly using when reality is used, for having many disappearances and inconvenience, as:

(1) wrench body A is in the breaker slot B2 of braked wheel B, utilize elastic parts C4 to withstand sour jujube piece C, but elastic parts C4 do not fix, in operating process, produce easily and beat or beat, displacement, and can't shore sour jujube piece B smoothly, the motionless situation of operating process blocking takes place easily.

(2) wrench body A is when operation, if the turn meeting causes elastic parts C4 to hold sour jujube piece C counterclockwise, make sour jujube piece C be equipped in the ratchet A11 of storage tank A1 with ratchet C2, if during the clockwise turn of wrench body A, then forming sour jujube piece C inwardly contracts at breaker slot B2 place, and push elastic parts C4 with fixing groove C3, but when elastic parts C4 is subjected to sour jujube piece C compression, make the pushing tow of elastic parts C4 easily because of elastic-restoring force, and with sour jujube piece C with the ratchet A11 that ratchet C2 is fastened on storage tank A1, cause wrench body A turn smoothly.

So, how to solve the brake structure of commonly using wrench body and have the problem that is easy to blocking, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.
