Abstract
The utility model discloses a clamp mechanism of hand power formula penknife, including the protecgulum, the back lid, the chuck, the tight piece of three clamp with be used for driving chuck pivoted chuck actuating mechanism, the protecgulum covers to be connected with the back and just forms the cavity between the two, the tight piece of chuck and three clamp is located the cavity, chuck actuating mechanism includes knob and carousel, be provided with the mounting hole with the cavity intercommunication on the protecgulum, the knob is installed in the mounting hole with rotatable mode, be provided with a first hole of advancing on the knob, the carousel is located between knob and the chuck, knob and carousel fixed connection, carousel and chuck fixed connection, the advantage is when rotating the knob, and the carousel rotates along with the knob, and meanwhile, the chuck also rotates under the drive of carousel together, realizes the drive of chuck from this, because the knob is installed in the mounting hole of protecgulum with rotatable mode, can can not result in the whole volume increase of hand power formula penknife at the outside bellying that forms of protecgulum, and security and aesthetic property are all better.
Description
Technical field
The utility model relates to a kind of pencil holding mechanism, especially relates to a kind of pencil holding mechanism of hand pulling type penknife.
Background technology
Hand pulling type penknife generally includes pencil holding mechanism and penknife structure.When sharpening a pencil, pencil enters in penknife structure through after pencil holding mechanism, and pencil clamps by pencil holding mechanism, and after pencil sharper is good, pencil unclamps by pencil holding mechanism, now pencil can be taken out.
The pencil holding mechanism of existing hand pulling type penknife generally includes protecgulum, bonnet, chuck, three clamps and the chuck drive mechanism for drive chuck rotation, protecgulum is connected with bonnet and forms chamber between the two, chuck and three clamps are positioned at chamber, protecgulum, bonnet and chuck are respectively arranged with pen-laying hole, three clamps are evenly distributed on around the pen-laying hole of chuck, and three clamps can be gathered pencil clamping with the rotation of chuck or separately be unclamped by pencil.At present, chuck drive mechanism is generally and is arranged on a bar shaped handle on chuck, this bar shaped handle is fixedly connected with chuck and reaches from the upper surface of protecgulum or side that it is outside, and as shown in Figure 1, user carrys out drive chuck when sharpening a pencil by turning handle and rotates its contour structures.
But, there is following problem in the pencil holding mechanism of existing hand pulling type penknife: the bar shaped handle in pencil holding mechanism stretches out the upper surface of protecgulum or a part for side forms lug boss in protecgulum outside, pencil holding mechanism external volume increases, cause that hand pulling type penknife overall volume increases, security is poor thus, aesthetic property is also poor.
Summary of the invention
Technical problem to be solved in the utility model is to provide one and hand pulling type penknife overall volume can not be caused to increase, the pencil holding mechanism of all good hand pulling type penknife of security and aesthetic property.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of pencil holding mechanism of hand pulling type penknife, comprise protecgulum, bonnet, chuck, three clamps and the chuck drive mechanism for driving described chuck to rotate, described protecgulum is connected with described bonnet and forms chamber between the two, described chuck and three clamps are positioned at described chamber, described chuck drive mechanism comprises knob and rotating disk, described protecgulum is provided with the installing hole with described chamber, described knob is arranged in described installing hole in a rotatable manner, described knob is provided with the first pen-laying hole, described rotating disk is between described knob and described chuck, described knob is fixedly connected with described rotating disk, described rotating disk is fixedly connected with described chuck.
Described protecgulum trailing flank is provided with three connecting pins, described chuck hub place is provided with second pen-laying hole coaxial with the first described pen-laying hole, the edge of described chuck is provided with three equally distributed recesses, described chuck is provided with the gathering sill of three arcs, three clamps are between described chuck and described bonnet and be evenly distributed on around the second described pen-laying hole, each described clamp is respectively arranged with a jack and a bayonet lock, the bayonet lock one_to_one corresponding of three clamps is positioned at three recesses, the jack of three clamps is communicated with three gathering sill one_to_one corresponding, insert in jack after three connecting pins insert gathering sill successively.
Compared with prior art, the utility model has the advantage of that chuck drive mechanism comprises knob and rotating disk, protecgulum is provided with the installing hole with chamber, knob is arranged in installing hole in a rotatable manner, knob is provided with the first pen-laying hole, rotating disk is between knob and chuck, knob is fixedly connected with rotating disk, rotating disk is fixedly connected with chuck, as the knob, rotating disk rotates with knob, meanwhile, chuck also rotates together under the drive of rotating disk, realize the driving of chuck thus, because knob is arranged in the installing hole of protecgulum in a rotatable manner, lug boss can not be formed in protecgulum outside, hand pulling type penknife overall volume can not be caused to increase, security and aesthetic property are all better.
