Abstract

The utility model discloses a replaceable spanner. The replaceable spanner comprises a T-shaped handle composed of a transverse rod and a vertical rod. The bottom end of the vertical rod is provided with an installing base, an inserting hole is formed in the middle of the bottom face of the installing base, and a detachable spanner head is arranged inside the inserting hole. The replaceable spanner is convenient to store and carry, and operation can be carried out effortlessly.

Description

A kind of changeable type spanner

Technical field

The utility model relates to a kind of manual five metals, especially relates to a kind of changeable type spanner.

Background technology

In all kinds of moulds, equipment, being connected and fixed of relevant spare and accessory parts usually used screw with stablizing of guaranteeing to install, and prevents from becoming flexible.Yet when installing, dismantling parts, due to aspects such as component structural, positions, the fastening and back-out of screw is all a difficult problem.While adopting on open market commercially available wrench operated, not only relatively consume power consuming time, and the corresponding different size of each inner hexagon spanner, therefore deposit and carry the comparatively inconvenience that also seems.

As Chinese patent Granted publication number: CN200970732, November 7 2007 Granted publication day, a kind of die nut is disclosed, this spanner one end forms ball head, and lateral circle surface forms a ring neck in adjoining ball head, wherein ball head peripheral ring is established and is formed a hex surface, and is inwardly provided with a storage tank in hex surface more than one of them, the notch of this storage tank is slightly less than groove body, and is outwards sequentially provided with a spring and an inner side is subject to spring push and outside to expose the little steel ball of storage tank in interior.Use this die nut to carry out when fastening, can only singlehanded by spanner, screw, relatively effort, and a whole set of spanner is comparatively heavy when carrying, wasting space comparatively while depositing.

Utility model content

The utility model is comparatively to require great effort, deposit and carry the comparatively deficiency of inconvenience in order to overcome when the spanner of prior art uses, provide a kind of operation comparatively laborsaving, deposit and carry changeable type spanner comparatively easily.

To achieve these goals, the utility model is by the following technical solutions:

A kind of changeable type spanner of the present utility model, comprises the T shape handle that cross bar and montant form, and the bottom of described montant is provided with mount pad, and the middle part of described mount pad bottom surface is provided with jack, is provided with dismountable spanner in described jack.Handle consists of cross bar and montant, and during use, both hands act on cross bar, thereby rotates T shape handle, and when fastening bolt, both hands are exerted oneself simultaneously like this, compare one-handed performance, seem comparatively laborsaving.Mount pad bottom surface arranges jack, thereby can replace bolt or nut that spanner adapts to different specification size, and the replacing of spanner also more for convenience.Therefore only need to manufacture T shape handle and some spanners, and without each specification being manufactured to handle, greatly save the use of material.While depositing, reduced the required space taking meanwhile.Overall weight is also lighter, is convenient to carry.

As preferably, described spanner comprises outer-hexagonal post and conical grip, and described conical grip is coaxial with outer-hexagonal post, and described jack is the bellmouth that outer imperial palace is little.Utilize the conical grip part of spanner and bellmouth to adaptation, thereby spanner is positioned, the axiality of spanner and montant is also better.When rotating T shape handle, the outer-hexagonal post part of spanner is consistent with the pivot center of montant, so bolt and spanner stressed comparatively stable in rundown process, reduces the damage of spanner to bolt.

As preferably, described cross bar and montant are all cylindrical, between cross bar and montant, are welded and fixed.Cross bar and montant are by being welded and fixed, and both connections are comparatively solid and reliable.

As preferably, the upper end of described jack is provided with the sled hole being communicated with jack, and the axis in described sled hole is perpendicular to the axis of jack and along radially running through montant, and the top of described conical grip is provided with and prizes the handle body matching in hole.Handle body enters into sled Nei，Qiao hole, hole by jack and on the one hand handle body is carried out spacingly, prevents that it from rotating, thus staff for the force transmission of T shape handle to spanner.At replacing spanner, be, can utilize the objects such as angle bar to insert the space in sled hole, by the method for knocking, spanner is released from jack.

As preferably, described sled hole is on mount pad surface along the axial arranged Long Circle of mount pad, and the width of described sled hole at mount pad center is less than the width on mount pad surface.Oblong sled hole makes the space of spanner handle body top larger, convenient by the spanner release in hole.

Therefore, the utlity model has following beneficial effect: when (1) carries out bolted by T shape handle, can operate by both hands simultaneously, comparatively laborsaving; (2) bolt that adapts to different size specification by changing different spanners carries out fastening, and adaptability is higher; (3) space taking while depositing is less, comparatively light while carrying.

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is the partial sectional view of the utility model mount pad;

Fig. 3 is the structural representation of spanner of the present utility model.

In figure, T shape handle 1, cross bar 1a, montant 1b, mount pad 2, spanner 3, outer-hexagonal post 3a, conical grip 3b, handle body 3c, jack 4, sled hole 5.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

In embodiment as shown in Figure 1, a kind of changeable type spanner, comprises T shape handle 1 and spanner 3, and T shape handle comprises cross bar 1a and montant 1b, and cross bar and montant are all cylindrical.The upper end of montant and the middle part of cross bar are fixed by welding, and the bottom of montant is provided with mount pad 2.Mount pad flare, as shown in Figure 2, the middle part of mount pad bottom surface is provided with jack 4, is the little bellmouth of outer imperial palace, and jack and montant are coaxially arranged.The upper end of jack is provided with the sled hole 5 being communicated with jack, and sled hole is along radially running through montant, and the axis of its axis and jack is perpendicular.Sled hole is on mount pad surface along the axial arranged Long Circle of mount pad, and its width at mount pad center is less than the width on mount pad surface.As shown in Figure 3, spanner comprises outer-hexagonal post 3a and conical grip 3b, and conical grip is coaxial with outer-hexagonal post, and the top of conical grip is provided with and prizes the handle body 3c matching in hole.

When reality is used, first the conical grip of spanner is partly inserted in the jack of mount pad, now, the handle body at conical grip top divides to extend into be prized in hole, the outer surface of conical grip and the inwall of jack fit, spanner and jack are coaxially felt relieved, by both hands rotating horizontal pole, carry out bolted afterwards.When needs are changed spanner, only need utilize the objects such as angle bar to be inserted in the space in sled hole, offset with the handle body at spanner top, by knocking, spanner is released from jack, change other spanners.
