Description

Pencil sharpener rocking handle

Technical Field

The utility model belongs to the technical field of the pencil sharpener structure, concretely relates to pencil sharpener rocking handle.

Background

In the stationery market, a hand-operated pencil sharpener is a very convenient pencil sharpening tool. The hand-operated pencil sharpener drives an internal transmission mechanism to drive a hob to sharpen a pencil through a pencil sharpener rocking handle. The pencil sharpener rocking handle comprises a rocking handle body hinged on the pencil sharpener shell, the end part of the rocking handle body is connected with a stress application rod, and the end part of the stress application rod is rotatably sleeved with a cylindrical handle knob. When the rocking handle is used, a user holds the cylindrical handle knob by fingers to rock the rocking handle body. The cylindrical handle knob part of the conventional pencil sharpener is generally fixed by a screw, the screw is easy to loosen after the pencil sharpener is used for a period of time, and a user needs to screw the screw at intervals, so that the pencil sharpener is very inconvenient. In response to this problem, a variety of improved constructions for the handle of penknife have been developed. For example, chinese patent No. 201721267829.3 discloses a hand-operated pencil sharpener handle which axially retains a cylindrical knob portion by a screw-like fastener which uses a barb structure on the outside of a cylindrical connecting portion in place of the screw thread structure. Although the structure is convenient to install, the barb structure of the structure is fastened through elastic deformation, and when the cylindrical knob part rotates, the barb structure still has a component force which is outward in the axial direction on the fastening piece, so that the fastening piece is loosened outward in the axial direction. For example, the rocking handle structure of the hand-operated pencil sharpener and the pencil sharpener disclosed in chinese patent No. 201720822698.4 realize the axial position limitation of the knob part by the cooperation of the position-limiting part provided at the outer end of the crosspiece (the reinforcing rod) and the position-limiting surface provided on the knob part. However, the limiting part arranged at the outer end part of the crosspiece (stress application rod) of the structure is formed by extruding and softening the outer end part of the crosspiece (stress application rod) through the arc concave surface of the metal spinning rod by means of the rapid rotating friction of the metal spinning rod on the outer end part of the crosspiece (stress application rod). However, the structure processing is very troublesome, the rotation and the pushing-down driving of the metal spinning rod need a set of complex and expensive equipment, and the processing process also needs to accurately position the rocking handle, otherwise, the shape of the limit part formed by processing is deviated, which can cause the unsmooth rotation of the handle knob part and seriously affect the product quality.

The utility model aims at providing a pencil sharpener rocking handle with convenient assembly and stable quality.

According to the utility model provides a pencil sharpener rocking handle, rocking handle main part including the plastics material, the one end of rocking handle main part is the application of force pole, the rotatable cover of tip of application of force pole is equipped with cylindric knob portion, its characterized in that the tip extension of application of force pole is equipped with a plurality of jack catchs, the jack catch with application of force pole integrated into one piece, the jack catch with the axis of application of force pole sets up for central annular array, the inner wall of cylindric knob portion be equipped with the spacing convex shoulder of jack catch complex annular.

The force applying rod with the clamping jaws is integrally formed when the whole rocking handle main body is manufactured, so that the assembly precision can be ensured, the manufacturing is simple, and the manufacturing cost can be reduced; during the assembly, only need form cylindric knob portion to insert along the axial of atress pole, the inner wall through cylindric knob portion makes the inside elastic shrinkage of jack catch warp, reach the spacing convex shoulder department of annular of cylindric knob portion inner wall up to the jack catch, the jack catch resumes outwards to pop out and blocks the spacing convex shoulder of annular under the elastic action, thereby it is spacing to realize the axial of cylindric knob portion, whole assembling process is very simple and convenient, can guarantee that long-term back cylindric knob portion of using can not loosen yet and take off, and the product quality is improved.

Further, for the convenience of the sliding assembly of the inner walls of the clamping jaws and the cylindrical knob portion and the smooth rotation of the cylindrical knob portion after assembly, the outer edges of the end portions of the clamping jaws are arranged to form cambered surfaces.

Further, the jack catch is three and is the article style of calligraphy and arranges, can guarantee stability.

Further, the stress application rod comprises a main body section and a clamping section, the main body section is a conical body, the clamping section is a cylindrical body, and the clamping section is connected with the clamping jaws. The stress application rod with the structure is matched with the inner wall of the cylindrical handle knob part with the matched shape, so that the stress application rod can be assembled conveniently and the cylindrical handle knob part can rotate smoothly after the stress application rod is assembled.
